NEW OR NOTEWORTHY PHILIPPINE PLANTS, XVII 



By Elmer D. Merrill 

 Director and Botanist, Bureau of Science, Manila 



The last paper of this series was published in 1920.^ In the 

 present paper one hundred six new species are described 

 from various parts of the Philippines, while a redescription of 

 Ficus argentea Blanco is included. This species, previously 

 known only from Blanco's imperfect description, on receipt of 

 material agreeing with his description in all essentials proves 

 to be a valid one. Polychroa Loureiro is accepted as the proper 

 generic name for the group long known as Pellionia Gaudichaud, 

 while the few Philippine forms formerly placed in Polytrema 

 are now transferred to Hallieracantha. Three genera, Pyrena- 

 ria, Pleipcarpidia, and Cowiea, the latter a recently described 

 genus previously known by a single species in British North 

 Borneo, are recorded from the Philippines for the first time. 

 A few notes on nomenclature are included, which involve some 

 changes in specific names.
